Job description

Nautilus is the first modern platform built for car washes, replacing expensive legacy systems that cost operators thousands monthly. Nautilus delivers mobile-first e-commerce, membership management, and automated marketing. Learn more at www.nautilus.co

Nautilus is the AI native all-in-one platform for the car wash industry. We’re the fastest-growing and most advanced tech company in car wash. The bar in this industry has historically been low — we’re here to raise it. We ship software that operators actually love, and it shows: we have the highest revenue per headcount of any team in the space, and the industry’s most respected customers on our roster.

Our product covers marketing, automations, payments, AI agents, reporting, infrastructure and a lot more. We’re growing fast, and our customers need someone who can own their experience end-to-end — triaging issues, debugging real technical problems, and turning support into a competitive advantage. This isn’t a “read from a script” support role; you’ll talk to customers every day, work directly in the product, in the logs, and alongside engineering to ship fixes.

We’re hiring a Customer Support Engineer to be the technical backbone of our customer experience. If you want high ownership, high impact, and a small team that punches way above its weight, we’d love to talk.

We’re backed by Rebel Fund (invests in roughly the top 10% of YC startups), Script Capital (Gamma, Patreon, OpenPhone), Blast Capital, Y Combinator, and some of the best Angels in the world.

You might be a fit if the below interests you:

• You’re high agency — you see a problem and fix it without waiting to be told, and you own outcomes end‑to‑end
• You love talking to customers and get real satisfaction from turning a frustrated operator into a fan
• You thrive in a high‑growth environment — fast pace, shifting priorities, and lots of greenfield don’t scare you, they excite you
• You have strong technical fundamentals — you’re comfortable in APIs, SQL, and logs, and know where you’re great and where you’re growing
• You’d rather fix the root cause and write the doc than answer the same ticket twice
• You’re in SF or willing to relocate, love working in‑person, and want to help build a culture we’ll all be proud of
• You want to join a strong technical team of product‑focused founders
• You want to conquer an entire industry

Our stack: Next, TypeScript, distributed systems, durable execution, custom tooling
